Correlation Between Intracranial Arterial Calcification and Imaging of Cerebral Small Vessel Disease
Conclusion: Intracranial artery calcification is common in patients with ischemic cerebrovascular disease and the intracranial carotid artery is most frequently affected. Intracranial arterial calcifications might be associated with imaging markers of SVD and are highly correlated with WMHs, lacunes, and CMBs. Quantification of calcification on CT provides additional information on the pathophysiology of SVD. Intracranial arterial calcification could act as a potential marker of SVD. Introduction Atherosclerosis is a systemic vascular process that is considered a major cause of cerebrovascular and cardiovascular di...

Device that measures cell strength could help identify drugs for asthma, hypertension and muscular dystrophy
Engineers, doctors and scientists at UCLA and Rutgers University have developed a tool that measures the physical strength of individual cells 100 times faster than current technologies.The new device could make it easier and faster to test and evaluate new drugs for diseases associated with abnormal levels of cell strength, including hypertension, asthma and muscular dystrophy. It could also open new avenues for biological research into cell force. It is the first high-throughput tool that can measure the strength of thousands of individual cells at a time.“Our tool tracks how much force individual cells exert over time...

Hypertension in the elderly.
Abstract After 80 years old, antihypertensive treatment significantly reduces cardiovascular events. In the elderly, blood pressure target depends on patients' frailty. After 80 years, French guidelines propose to aim a SBP<150 mmHg without orthostatic hypotension and without exceeding the prescription of more than three antihypertensive drugs. The target may be more ambitious for robust elderly patients. The new 2018 European guidelines set: a stricter target for robust elderly patient aged 80 years or older (SBP between 130 and 139 mmHg and DBP between 70 and 79 mmHg); this objective is less strict for frail ...

Impaired Activity of Ryanodine Receptors Contributes to Calcium Mishandling in Cardiomyocytes of Metabolic Syndrome Rats
Conclusion Principal findings of this work are that abnormal Ca2+ transient amplitude, contractile dysfunction; and impaired relaxation of MetS cardiomyocytes underlies intrinsic dysfunctional RyR2 and SERCA pump. Abnormal activity of RyRs was evidenced by its decreased ability to bind [3H]-ryanodine. Although the MetS condition does not modify RyR2 protein expression, its phosphorylation at Ser2814 is decreased, which impairs its capacity for activation during ECC. The dysfunctional RyRs, together with a decreased activity of SERCA pump due to decreased Thr17-PLN phosphorylation suggest a downregulation of CaMKII in MetS...

Pollutants In Your Salt!?
Your doctor, the media, and the medical establishment continue to warn that flavoring your food with salt will kill you. They link sodium consumption to a higher risk of high blood pressure, stroke – and of course, heart disease. As usual, the powers that be are missing the real picture… You see, salt has been part of human life for thousands of years – long before these chronic diseases became as common as they are today. Humans started adding salt to their food for more than 5,000 years. It was the most effective way to preserve food. Some historians even go as far as to credit salt for the development of human civ...
